I worked in the BOD lab, 2nd shift, at the MWRD in Stickney. I was transferred from the Egan facility in Schaumburg, Il. It was a difficult job, because it required learning to operate a half dozen different labs. The BOD lab was the biggest of all the labs. The solids lab was easy, it required just one operator. Before working at the MWRD, I was a Q/C chemist for Shell, Great Lakes Terminal in Bedford Park Il. The lab job at Shell was much easier, because it was only one lab. Shell paid much better too. I would still be there, but they shut down operation in March 2004.
No, it really is! If you view the canal where the water comes out of the plant, you will see that the wildlife is very active around the water coming from the plant - way more than anywhere else in the canal. It comes out very clean and oxygenated which the fish and birds and bugs love!
Yes, David St. Pierre normally has a dick in his mouth. This section of video was very out of character for him. It must have been very uncomfortable for him without his pacifier.
hey Stickney lets use plants to clean are drinking water and are poo to make compost and are pee to fertiliz are plants and to grow food and for people gradens lets go green and help are planet
@@roadmaster720 yes, lime treatment is a nightmare. Messy and horrid ammonia fumes. Lots of breakdowns. Class A with pellitizing has had some success. Deer Island brags about their success. I don't know how much they make off of it. Synagro was pushing their process for a while. My old planet used Zimpro WAO process. Just flatten the cells and kill the pathogens. 390°F at 650 psi. Works well, but needs a lot of maintenance. Good cake at 55%TS. VS reduction in the high 50s. Only good for sod, strip mine filling and clean landfill cover. No nutrients, they get destroyed in the process. How do you dispose of your ash? ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-HT4RainY-lYw.htmlith plate and frame presses ~55%ts. VS reduction in the high 50s.
the ash exhaust from the incinerator goes thru the venturi to be wetted down, settles to the venturi bottom and pumped to a small clarifier to thicken same. water decants for the top over the weir and back to plant headworks and ash slurry pumped to a onsite lagoon formerly used for digested sludge 25 yrs worth before the incinerator and alkaline stablization was built and used.we used the venturi to regulate the freeboard pressure in the fluidized bed incinerator. yes, lime treatment is a nightmare. the n-viro method we used mixed the cement kiln dust and lime kiln dust with the dewatered sludge in the prescribed ratio's. we would set the plc for the ratios. start the process with eyes on the amp gauge to monitor the work the auger and motor was doing. amp increasing rapidly meant clogging was starting. you had to be on your toes at all times. after mixing and discharge to the holding bin, the process was to let the nutri-lime exotherm to 90 centigrade, hold for 12 hrs to kill the pathogens. the 12 hr hold time started when the pile reached 90cent. after 12 hrs it was moved outside and kept until needed. the horrid ammonia fumes was murder. that ammonia smell smelled like a ripe cat litter times 100.dusty/nasty process. incineration always better the biggest PIA was when the mixing auger stopped up and the chemical feed lines. dealing with the clogs was nasty. the worst was the mixing auger where everything come together. it would jam up tight and take forever to break up that clog. i injured my back trying to use a heavy pry bar unstopping that auger chute and was out on worker's comp for almost 3 mths.clean up of the pit after a run of nutri-lime was hard,nasty and a PIA as you can imagine. i've been retired 6 years now from the wwtp i worked in. don't miss it at all. especially the nutri-lime part.
